Relieve all tension and de-energize any associated equipment before removing or installing the spring. Use appropriate pliers or spring hooks to seat cross-over ends without overstretching beyond the maximum extended length of 6.06 inches, as exceeding this dimension can permanently deform the spring. Follow applicable equipment manufacturer service procedures and local mechanical codes during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Cross-Over\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0348 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Free Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 6.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.96 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 3.81 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E34C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51994897514802,"sku":"E34C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d9690e51df3e87ea5ca2fd593783681.jpg?v=1789992250","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e34c-extension-spring-3-81-lb-0-375-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
